Stick framing is the more common type of roof framing, accounting for 60% of all roofs. This is likely due to the fact that it is a more traditional method of framing and is less expensive than truss framing. Truss framing is a newer method of framing that uses prefabricated trusses to create the roof structure.<\/p>\n
Source<\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n\n In order to do roof framing properly, it is important to understand the unique shape and dimensions of your roof, since these will greatly impact the geometry of the roof frame.<\/p>\n Within the roofing industry, there are two basic types of roof framing:<\/p>\n Each of these utilizes a fundamentally different approach to building the roof frame.<\/p>\n For example, in the case of stick framing, you will use ordinary lumber for your rafters and beams, and then build the frame one beam at a time. In the case of truss framing, you will use pre-made triangular-shaped wood pieces to build the roof frame.<\/p><\/blockquote>\n Thus, at the very outset, you must make a decision of whether you want to go with the traditional, more labor-intensive stick framing process, or whether you\u2019d prefer to use the newer, less labor-intensive truss framing process.<\/p>\n <\/p>\n If you take a quick look at the various houses in your neighborhood, you\u2019ll probably notice a variety of roof shapes<\/a>. The most common of these roof types include the following: gable, hipped, mansard, gambrel and flat.<\/p>\n Sometimes you see a combination of two or more styles used on the same roof, such as the case of a hipped roof<\/a> with a gabled dormer.<\/p>\n So, as you can probably imagine, each different type of roof will require a different type of roof frame. Generally speaking, the simpler the roof type, the easier it is to build a roof frame to support it.<\/p>\n However, even a relatively common roof type<\/a> \u2013 such as the gabled roof \u2013 can be made more complex with the use of overhangs, hips and dormers.<\/p>\n If you think about this problem from a purely geometrical perspective, you can understand why this makes sense: each little twist or variation on a common triangle shape (i.e. the standard gable roof shape<\/a>) will require additional calculations and preparation work ahead of building the frame.<\/p>\n As a result, it\u2019s possible to make the following bold assertion: truss framing is really only appropriate for gable and hip roof<\/a> types; for all other roof types<\/a>, you should use the stick framing approach.<\/strong><\/p>\n That\u2019s because the truss framing approach relies on pre-made, pre-cut shapes that may or may not fit your roof\u2019s actual dimensions. Also, if you are planning on making additions or modifications to your roof at a later date, it is preferable to use the stick framing approach.<\/p>\n As noted earlier, roof framing is really all about getting the geometry of your roof correct. Thus, it is important to understand how each of the following calculations will impact the roof framing process:<\/p>\n Let\u2019s consider each of these terms in the context of a traditional gabled roof. Span refers to the full measurement across the top of your building, from one exterior wall to the other exterior wall.<\/p>\n Once you know the span, you can then calculate the rise. The rise is the measurement from the center point of the span to the top of the roof. In the case of the gabled roof, this will be the \u201cpointy tip\u201d where there two sides of the roof meet.<\/p>\n Next, you can calculate the run, which is simply one-half the measurement of the span.<\/p>\n If you are thinking in terms of geometry and triangles, as you must when you take on a roof framing project, then the line length is simply the hypotenuse of the triangle defined by the rise and the run.<\/p>\n You can measure it from the exterior wall where the span ends to the very top of the rise.<\/p>\n The final calculation, the pitch, can be understood as the amount of angle or slope that the roof<\/a> has. Mathematically, it is simply \u201crise over run,\u201d telling you exactly how high a roof rises for every unit of run.<\/p>\n In the roofing industry, it is customary to define \u201crise over run\u201d in terms of 12. This 12 corresponds to 12 inches, or 1 foot. Thus, if a pitch is 4\/12<\/a> it means that the roof rises 4 inches for every 12 inches of span.<\/p>\n Pitch can be either shallow or steep, depending on the needs of the roof. For example, in areas of the country where snowfall is abundant, it makes sense to create a steeper pitch in order to make snow removal<\/a> easier.<\/p>\n If you are using the stick framing approach, you will now need to spend time measuring and cutting the rafters based on the calculations you just made.<\/p>\n There are several different methods for doing this, but by far, the most popular method uses the traditional framing square. Using the traditional framing square and the calculations from earlier, you can lay out the rafters appropriately.<\/p>\n In terms of cutting the rafters, there are three basic types of cuts that you need to know:<\/p>\n Each of these cuts determines how two different pieces of wood will interlock and fit together to form one sturdy frame.<\/p>\n As you can see, the initial plan for framing your roof needs to take into account several key variables, such as the shape of the roof<\/a> and any relevant community building codes.<\/p>\n You will then have to choose between two very different types of roof framing (stick framing vs. truss framing).<\/p>\n Once you have done that, it\u2019s time to make all of the precise calculations required for the pieces of wood to fit together appropriately.<\/p>\n The goal, of course, is for every part of your roof frame<\/a> to fit together perfectly, such that you have the perfect support for your new roof.<\/p>\n","protected":false},"excerpt":{"rendered":" One of the most important parts of building a sturdy roof is the initial roof framing plan.
